History

The 51st Fighter Group spent most of the Second World War defending the two ends of the "Hump", the air supply route between India and China. The unit had been activated in January 1941, nearly a year before American entered the war. It was one of the first groups dispatched from the United States after Pearl Harbor, traveling west to India via Australia and Ceylon.

In 1942 the Tenth Air Force was responsible for both India and China. The first 51st FG unit to actually see service was the 16th Fighter Squadron, which was detached to serve with the 23rd FG.

The rest of the group moved forward to Dinjan, in Assam, in September 1942, beginning operations in October. Dinjan was well within range of Japanese aircraft, and so the 51st spent part of its time defending the "Hump" and part defending its own bases. It also took part in the fighting during the Japanese offensive in northern Burma in 1943.

In October 1943 the 51st FG was transferred to the Fourteenth Air Force, and to China. Its duties now involved defending the Chinese end of the "Hump" as well as supporting the Chinese army. It also carried out attacks on Japanese shipping. The unit returned to India in September 1945, and then to the United States in November.
